Every legal entity in a corporate group across jurisdictions, from the GLEIF golden copy.

Tool description as the model sees it

Every entity in a corporate group, across all jurisdictions, in ONE call — built on the GLEIF golden copy (every Level 2 relationship record). Give any member of the group (LEI or company name): the tool climbs to the group’s ultimate accounting-consolidation parent and returns every entity that reports it as ultimate parent, every descendant over direct-parent links, and the international branches of any of them. Aggregates are over the WHOLE group (member_count, jurisdiction_count, by_jurisdiction); the member list is capped by limit and says so. Each member carries depth below the root, direct_parent_lei, consolidation % where reported, jurisdiction and LEI status.

Parameters

Name	Type	Required	Description
`lei`	string	yes	A 20-character LEI of ANY group member, e.g. “W38RGI023J3WT1HWRP32” (Siemens AG), OR a company name, e.g. “Siemens” — resolved against the GLEIF entity register (a subsidiary match still lands on the whole group). Do not construct an LEI.
`limit`	number	no	Max members to list, 1-2000 (default 300). Counts and by_jurisdiction always cover the whole group.
